Test Class for Trigger

Hi Experts,

below is my trigger, i need test class for my trigger.


trigger CreateChargeCodeAutomatically on MPM4_BASE__Milestone1_Project__c (after insert) {
    
    Set<Id> projectidWherechageCodeExist= new Set<Id>();
    Set<Id> prjIdSet= new Set<Id>();
    for(MPM4_BASE__Milestone1_Project__c prj :trigger.new){
       prjIdSet.add(prj.Id);
    }

    List<Charge_Code__c> chargeCodeList=[SELECT Id,Project__r.Id FROM Charge_Code__c WHERE ID IN :prjIdSet];
    if(chargeCodeList.size() > 0){
       for(Charge_Code__c chr :chargeCodeList){
         projectidWherechageCodeExist.add(chr.Project__c);
       }
    }

    prjIdSet.removeAll(projectidWherechageCodeExist);
    
    List<Charge_Code__c> listToCreate=new List<Charge_Code__c>();
    
    for(MPM4_BASE__Milestone1_Project__c prj :[SELECT Id FROM MPM4_BASE__Milestone1_Project__c WHERE ID IN : prjIdSet]){
       
       for(Project_Charge_Code__c chrge : [SELECT Id,Name FROM Project_Charge_Code__c ]){
            
            Charge_Code__c chrgg=new Charge_Code__c();
            chrgg.Charge_Code__c = chrge.Id;
            chrgg.Project__c = prj.Id;
            listToCreate.add(chrgg);
                   
       }
    }
    
    try{
        insert listToCreate;
    }
    catch(DmlException de){
       System.debug('@@@@SFDC::'+de);
    }

}


Thanks,

Please try below test class
  
@isTest
public class CreateChargeCodeAutomaticallyTest
{
    static testMethod void CreateChargeCodeAutoTest()
	{
		
		MPM4_BASE__Milestone1_Project__c milObj = new MPM4_BASE__Milestone1_Project__c();
			milObj.Name = 'Salesforce.com';
			// insert all Mandatory Field data
		insert milObj;

		Charge_Code__c chargeObj = new Charge_Code__c();
			chargeObj.Project__c = milObj.id;
			// insert all Mandatory Field data
		insert chargeObj;
		
		Project_Charge_Code__c projObj = new Project_Charge_Code__c();
			projObj.Name ='Test';
			// insert all Mandatory Field data
		insert projObj;
		
		Test.StartTest();

			MPM4_BASE__Milestone1_Project__c milObj1 = new MPM4_BASE__Milestone1_Project__c();
				milObj1.Name = 'Salesforce.com';
				// insert all Mandatory Field data
			insert milObj1;
		
		Test.StopTest();
		
    }
}

For test data please add all mandatory field for  MPM4_BASE__Milestone1_Project__c  ,Project_Charge_Code__c and Charge_Code__c object.
Please Remove Name field from all object if Name is autoNumber.

Hi Amit,

It showing Code Coverage 63%. Is it ok for trigger (or) we need to cover more than 75%.
Amit Chaudhary 8Amit Chaudhary 8
Hi Manu,

As per salesforce best pratice code coverage should be more the 75% but you can deploy your code with 63% also. Because limit is 75% more over all code coverage. 
List<Charge_Code__c> chargeCodeList=[SELECT Id,Project__r.Id FROM Charge_Code__c WHERE ID IN :prjIdSet];
    if(chargeCodeList.size() > 0){
       for(Charge_Code__c chr :chargeCodeList){
         projectidWherechageCodeExist.add(chr.Project__c);
       }
    }
It look like above code will not execute in your trigger as in below line you are using "prjIdSet" set in "Charge_Code__c " object ID (in where condition ) but in "prjIdSet" you are storing "MPM4_BASE__Milestone1_Project__c" object id. I hope you can remove above code from your trigger.

[SELECT Id,Project__r.Id FROM Charge_Code__c WHERE ID IN :prjIdSet];


Please mark this as solution by selecting it as best answer if this solves your Test class problem, So that if anyone has this issue this post can help

1% Coverage is sufficeint for Trigger Test class.
You can deploy it into Production.
